[thomas bonfort]

Peter,
The masking is supposed to work with WCS with GDAL outputformats, as
can be seen in our test suite:
full: https://github.com/mapserver/msautotest/raw/master/wxs/expected/wcs_20_getcov_full.tif
masked: https://github.com/mapserver/msautotest/raw/master/wxs/expected/wcs_mask_20_getcov_full.tif
# RUN_PARMS: wcs_mask_20_getcov_full.tif [MAPSERV]
QUERY_STRING="map=[MAPFILE]&SERVICE=WCS&VERSION=2.0.0&REQUEST=GetCoverage&COVERAGEID=grey&FORMAT=image/tiff"
> [RESULT_DEMIME]
